Identification of potentially zoonotic parasites in captive orangutans and semi‐captive mandrills: Phylogeny and morphological comparison
Cysts and trophozoites of vestibuliferid ciliates and larvae of Strongyloides were found in fecal samples from captive orangutans Pongo pygmaeus and P. abelii from Czech and Slovak zoological gardens. As comparative material, ciliates from semi‐captive mandrills Mandrillus sphinx from Gabon were included in the study. Phylogenetic analysis of the detected vestibuliferid ciliates using ITS1‐5.8s‐rRNA‐ITS2 and partial 18S ribosomal deoxyribonucleic…

A Survey on One Health Perception and Experiences in Europe and Neighboring Areas
A questionnaire survey was promoted under the COST Actions “ Network for Evaluation of One Health-NEOH” and “ European Network for Neglected Vectors and Vector-Borne Infections-EURNEGVEC” , from June 2016 to April 2017, to collect information on the existence of One Health (OH) collaboration and implementation of OH initiatives in 37 EU COST Countries. The questionnaire was to be answered by key respondents representing the three major OH compone…
Gastrointestinal protists and helminths of habituated agile mangabeys ( Cercocebus agilis ) at Bai Hokou, Central African Republic
Infectious diseases including those caused by parasites can be a major threat to the conservation of endangered species. There is thus a great need for studies describing parasite infections of these species in the wild. Here we present data on parasite diversity in an agile mangabey (Cercocebus agilis) group in Bai Hokou, Dzanga-Sangha Protected Areas (DSPA), Central African Republic. We coproscopically analyzed 140 mangabey fecal samples by con…

Gastrointestinal symbionts of chimpanzees in Cantanhez National Park, guinea‐bissau with respect to habitat fragmentation
One of the major factors threatening chimpanzees (Pan troglodytes verus) in Guinea-Bissau is habitat fragmentation. Such fragmentation may cause changes in symbiont dynamics resulting in increased susceptibility to infection, changes in host specificity and virulence. We monitored gastrointestinal symbiotic fauna of three chimpanzee subpopulations living within Cantanhez National Park (CNP) in Guinea Bissau in the areas with different levels of a…
The Effect of Low‐ and High‐Fiber Diets on the Population of Entodiniomorphid Ciliates T roglodytella Abrassarti in Captive Chimpanzees ( P an Troglodytes )
T roglodytella abrassarti is an intestinal entodiniomorphid ciliate commonly diagnosed in the feces of wild and captive chimpanzees ( P an troglodytes ). Entodiniomorphids could be considered to have a mutualistic relationship with the great apes, in that the ciliates benefit from the intestinal ecosystem of the host, while also contributing to the fiber fermentation process. We examined the effect of diet on the infection intensities of T . abra…
Molecular diversity of entodiniomorphid ciliate Troglodytella abrassarti and its coevolution with chimpanzees
The entodiniomorphid ciliate Troglodytella abrassarti is a colonic mutualist of great apes. Its host specificity makes it a suitable model for studies of primate evolution. We explored molecular diversity of T. abrassarti with regard to large geographical distribution and taxonomic diversity of its most common host, the chimpanzee. We found a very low diversification of T. abrassarti in chimpanzees across Africa. Distribution of two types of T. a…
Gastrointestinal Parasites of Indigenous and Introduced Primate Species of Rubondo Island National Park, Tanzania
A survey of entodiniomorphid ciliates in chimpanzees and bonobos
Intestinal entodiniomorphid ciliates are commonly diagnosed in the feces of wild apes of the genera Pan and Gorilla . Although some authors previously considered entodiniomorphid ciliates as possible pathogens, a symbiotic function within the intestinal ecosystem and their participation in fiber fermentation has been proposed. Previous studies have suggested that these ciliates gradually disappear under captive conditions. We studied entodiniomor…
Effects of high‐ and low‐fiber diets on fecal fermentation and fecal microbial populations of captive chimpanzees
We examined fiber fermentation capacity of captive chimpanzee fecal microflora from animals ( n =2) eating low‐fiber diets (LFDs; 14% neutral detergent fiber (NDF) and 5% of cellulose) and high‐fiber diets (HFDs; 26% NDF and 15% of cellulose), using barley grain, meadow hay, wheat straw, and amorphous cellulose as substrates for in vitro gas production of feces. We also examined the effects of LFD or HFD on populations of eubacteria and archaea i…
